Born and educated in England, Edward Osborn arrived in Seattle about 1910 and worked as a delineator for several well-known architectural firms. From 1920-1930, he occasionally worked as an independant designer. Osborn was known especially for his watercolor renderings. While design specifications exist for commercial projects that Osborn was either commissioned to design or those that he put out for speculative bids, the name A Auto Manufacturing Company does not appear among them. This plant was possibly not built.
